Welcome to Phase 1: Strong ROS 2 Engineer.
In this phase, you will build your core ROS 2 foundation step by step. We will start from setup and basic concepts, then move into nodes, topics, services, actions, parameters, launch files, YAML configuration, executors, QoS, lifecycle nodes, and finally a complete mini-project.
Please do not rush this phase. ROS 2 becomes easier only when the basics are clear. Try to follow the lectures in order, run the commands yourself, write the code, and observe the output in the terminal.
In this phase, your goal is not only to memorize commands. Your goal is to understand how ROS 2 systems are structured, how nodes communicate, how to debug problems, and how to think like a ROS 2 developer.
By the end of Phase 1, you should be comfortable building, running, debugging, and explaining a multi-node ROS 2 system.
